Our water filter will catch particles as small as 1 micron. It is fitted with hose ends ready to attach to your garden hose. Add a 6-7 ft section to reach into the drum, making filling your system easy. We have found that the use of our water filter when filling your automatic insect control system will extend the life of your nozzles and keep the your system operating at peak performance. The orifice size of our spray nozzles is 10 microns. A water softener will remove particles down to 50 microns (a "boulder" in comparison). One cartridge is included. Additional replacement cartridges are available online or by calling our office.
Shoo-Fly is affordable, and saves us money. I would give them 5 out of 5 stars. Truly a well-organized, well-thought-out product that each and every horse owner could be well served by.
